What ways have you observed a particular group of people or community being underserved or wronged?

Explanation:

Well repeat the question to yourself and ask have you ever seen that happen. This question is meant for you to be answered by. It's your opinion. If you haven't seen this happen then explain that you haven't. Hope this helps.

the sentence that avoid faulty coordination is:

culture, which is well represented in philadelphia, plays a major role including theatre, music, and the visual arts.  

faulty coordination occurs when the writer gives equal importance two different ideas (clauses) which in fact are not equivalent. in order to correct a misplaced clause or idea, the writer can place less important or emphatic ideas in a relative clause as in the previous sentence.
